The Canadian singer on husband Elvis Costello, her guilty pleasure and what you’ll find in her fridge.

A piano player since age four, the Grammy winner was mentored by Rosemary Clooney and she has performed with Tony Bennett. She’s married to British rocker Elvis Costello, with whom she has two-year-old twin boys. Her new album, Quiet Nights, features both ballads and blossa Nova classics. Here, the Canadian chanteuse gives us a backstage pass to her personal life.

Around the house, I sing . . . Barbra Streisand. [Krall is producing the legend’s next album, due this year.]

In my fridge you’ll find . . . this wood-smoked salmon that’s found in British Columbia.
I collect . . . Canadian art. I started doing that before I bought my first car—I’ve got my priorities straight.

The best thing about midlife is . . . I’m the happiest I’ve ever been.
